Application filed May 24,

and State of Connecticut, have invented av certain new and usefulPackage for Strip or Filamentary Material and Method of Forming theSame, of which the following is a specification.

' The invention relates to a new and useful form of package or containerfor strip or filamentary material'wound in cop or coil form and to themethod of forming the composite article comprising the coil of materialand the contalner for the same. To

this end the invention includes the formation of a tubular body,preferably'of paper or similar flexible material, having'its endsincised ina generally longitudinal direction to form a series of tabs orfingers, adapted first to be bent normal to the surface of the bodyportion to provide a generally spoollike element to receive theconvolutions of the filamentary or strip material, and, sec- 0nd, tohave the free ends of the tabs'or fingers bent or folded over theperipheral surface of the coil to substantiallyen'close the latter. Inthe preferred application of the method certain of the tabs or fingershave their outer ends bent over the surface of the coil before thelatter is completed and the ends of the remaining tabs or fingers foldedover the outer surface of the coil when the latter has beenpracticallycompleted, with the final con'vOlut-ions of 'the coil, the number ofwhich convolutions may vary according to the size and character of thepackage, being wound over the adjacent tab ends to lock the same intoposition, the whole constituting a package in which the tabs or fingersof the body portion or spool-like element are firmly interlocked betweenthe layers of the" coil to effectively maintain and preserve the formthereof, without, however, in anyway interfering with the readyunwinding of the coil, either in whole or in part. therefore involves,further, the production of the spool-like element or container including the central tubular body portion having the ends thereof splitor incised longitudinally to form bendable or foldable tabs, and,second, the container aforesaid The invention 1921. Serial No. 472,056.

having the filamentary or strip" material wound 1n a coil thereon withthe ends of the tabs disposed-as described, thewhole to constituteanovel and useful package including the container-end the coil of,materlal contained therein and enveloped thereby. I

The inventionis illustrated the accomy g gS, inwhich:

Fig. 1 is a blank from which the container is formed; I I a i Fig. 2 isan end elevation-of-the container with the filamentary material woundthereon; c

and i I ,c

Fig. 4 is a View similar to Fig. 3 showing the completed package, in itspreferred Referring to the drawings, lindicatesthe body ofthe'container, in the form of aJsheet of paper, cardboard or othersuitable flexi- ,ble material, thatis capable of being rolledsubstantially Fig. 8 is a vertical sectionon lined-r3 of I or formedinto tubular.shape, having kerfs or incisions extending from'itslateraledges toward the longitudinal axis of the sheet, leaving themiddle portion'thereofimperforate,"said kerfs or incisions dividing thesections of the sheet on eachside'of the imperforate'middlesection intoa series of tabs or fingers 2, which be readily bentl relatively to theplane of the sheet; The tabs or fingers 2 on each side are preferablybent along the lines where'they join themiddle portion of the sheetuntil :they are normal to the 'planeofthe sheet, so that when the latteris rolled into tubularwform the series of tabs or fingers on each sidewill form what are, in effect, end flangest'o the tul ularl body portionand the whole will constitute a spool-like element or device, as moreparticularly illustrated in Figs. 2 and 3, upon which filamentary orstrip-like material 3 may be wound in successive convolutions, either byhand or by machinery, the widthiof the 0011 being determined-by thelongitudinal dimen sion of the tubular body portion 1, and the thicknessof the coil being determined by the length of the tabs 2 and the extent,to which the latter are to overlap the surface of the coil. After thespoollike element has been thus formed, the filamentary 0r strip-likematerial 3 is wound in successive convolutions and layers on the tubularbody portion and between the flanges formed by the fingers 2. Preferablybefore the winding of the coil has been com-- pleted, the ends ofcertain of the tabs 2 are bent or folded over the peripheral surface ofthe coil, as shown in Fig. 4:, so that the ends of opposite tabs lieadjacent each other or may even overlap to a slight extent. Additionalconvolutions of the coil, as indicated at 4 in Fig. a, are then woundover the folded tab ends and when the coil has beensubstantiallycompleted the ends of the remaining tabs are similarlyfolded over the surface ofthe coil and secured in any convenient orpreferred manner, as, for example, by the application of acircumferential strip of fabric secured by an adhesive. A convenientmode, however, of securing the outer ends of the tabs is thatillustrated in Fig. 4, in which a final l yer or partial layer ofconvolutions of the filamentary or strip material is wound over theinwardly bent tab ends, as at 5, to lock the same firmly in position. Itwill be under stood that, instead of bending the ends of two sets oftabs on opposite sides of the container, three or more sets may be sobent, the ends of the tabs in each sucreeding set overlying coilsections varying dis-- tances from the axis of the coil, and by thusinterlocking the tab ends between several layers of the coil, theinherent strength and durability of the finished package will bematerially increased.

The completed package, if desired, may be suitably taped or encased inpaper or other appropriate material, but in many instances theconstruction as hereinbefore described will be found. to be sufficientfor ordinary commercial usage. It will also be apparent that theinvention is applicable to the packaging of various kinds of material infilamentary or tape form, such as threads, yarns, wires, flexible tubes,ribbons, and the ike, with the assurance that the proper shape of thecoil will be maintained and the material thereof be protected againstinjury, by. the particular mode of associating the container with thecoil.

What I claim is:

1. The method of packaging filamentary or strip material which comprisesforming tubular body of flexible material, slitting the ends thereof toform tabs, bending the tabs to constitute end flanges to the tubularbody, winding the filamentary or strip material on the body between theflanges, and bending the outer ends of the tabs to overlie the endsthereof to form tabs, bending the tabs to constitute end flanges to thetubular body, winding the filamentary or strip material on the bodybetween the flanges, bending the ends of certain of the tabs to overliean intermediate layer of the coil before the latter is completed, andbending the remaining tabs over the final layer of the coil. 7

3, The method of packaging filamentary or strip material which comprisesforming a tubular body of flexible material, slitting the ends thereofto form tabs, bending the tabs to. constitute end flanges to the tubularbody, winding the filamentary or strip material on the body between theflanges, bending the ends of certain of the tabs to overlie anintermediate layer of the coil before the latter is completed, bendingthe remaining tabs over the final layer of the coil, andwinding severalconvolutions of the coilto overlie the;

adjacent ends of the last tabs.

4.. A container for wound filamentary or strip material comprising atubular body portion, and tabs extending from the ends thereof adaptedto be folded or bent over the coil of i'naterial wound on the bodyportion.

A. container for wound filamentary or strip material comprising a tubeof paper or the like having its ends slit longitudinally to form tabsadapted to be folded or bent over the coil of material wound on the bodyportion.

6. An article of manufacture comprising tubular body havinglongitudinally split ends forming tabs, and a coil of filamentary orstrip material. wound on the tubular body, said tabs being folded orbent over the sides and outer peripheral surface of the coil. 7. Anarticle of manufacture comprising a tubular body having longitudinallysplit ends forming tabs, anda coil of filamentary or strip materialwound on the tubular body, certain of said tabs being folded or bentover and interposed between successive intermediate layers of the coil,and other tabs having their ends bent over the outer peripheral. surfaceofthe coil. v Signed New Haven in the county of New Haven and StateofConnecticut this 22nd day of April A.
